Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If sensor information is used to calculate the position of the mobile body, then unmanned driving control is enabled, but detection precision decreases when another object overlaps the mobile body
Solution Approach 1:
The patent introduces disturbance information as an intermediary element that mediates between the sensor detection process and the control system. By acquiring disturbance information about external factors before they affect detection, the system can adjust its processing to maintain precision. The disturbance information acts as a mediator that allows the system to compensate for the presence of overlapping objects without sacrificing automated driving control capability.
2Measurement precision
If communication with the outside is used for unmanned driving control, then control accuracy is improved, but system reliability decreases when communication trouble occurs
Solution Approach 1:
The patent applies preliminary action by acquiring disturbance information in advance before communication troubles occur. The control device proactively obtains information about potential external factors that may affect communication or detection, and uses this information to prepare alternative control strategies. This allows the system to switch to modes that don't rely on external communication when troubles occur, maintaining reliability while preserving control accuracy through pre-prepared solutions.
Solution Approach 2:
The patent changes the operational parameters of the control system based on disturbance information. When communication troubles are detected or anticipated, the system transitions between different control modes (e.g., from cloud-dependent autonomous driving to local decision-making modes). This parameter change allows the system to maintain appropriate control accuracy adapted to the current communication condition, ensuring reliability across varying operational environments.

AI summary
A control device for controlling an action of a movable body that can be moved by unmanned driving includes an acquisition unit that acquires disturbance information regarding an external factor that affects control of the unmanned driving and is different from the external factor of the mobile body, and a control unit that changes a control form of the action of the mobile body using the disturbance information.
